I have a window in my HT that is about 90" long and 36" high. I currently have the Kathy Ireland blackout cellular shades in my living room upstairs and they are not wireless, but they sure block out the light. I was looking at getting shades that are black on the inside and white on the outside. Don't want anything that requires power as there is no outlet near it. Need something that runs on a battery.

I know they have a wireless batter option, but was wondering if anyone has tried them and or if I could get better for cheaper. LOL.
